“Hacktivists Starting Cyber Attack against Israel on 7th of April,” Anonymous wrote on Twitter, calling on hackers around the world to join up for a second ‘OpIsrael.’

Israeli government agencies are reportedly readying for the attack: “It’s something being organized online over the past few days. What distinguishes this plan when compared to previous attacks is that it really seems to be organized by Anonymous-affiliated groups from around the world in what looks like a joining of forces,” Ofir Ben Avi, director of online group Accessible Government told Haaretz.

The first ‘OpIsrael’ cyber-attacks were launched by the hacktivist group during Israeli’s ‘Pillar of Defense’ assault on Gaza in November 2012.

“We are Anonymous. We are legion. We will not forgive. We will not forget. Israel, it is too late to expect us,” their message to Israeli authorities read.
